Which phrase correctly expands the acronym ME in engineering roles?

• A. Mechanical Engineering Director
• B. Mechanical Engineer of Record
• C. Mechanical Engineering Officer
• D. Mechanical Supervising Engineer

Answer: (B)

In engineering roles, ME is commonly understood as Mechanical Engineer of Record. The Engineer of Record is the licensed professional who takes formal responsibility for the mechanical design, seals and signs the project drawings, and ensures the work complies with applicable codes, standards, and contract requirements. This designation carries legal accountability for the design documents and their safety and compliance.

That’s why the expansion Mechanical Engineer of Record is the best choice: it explicitly conveys both the professional credential (Engineer) and the official responsibility (of Record) for the project’s mechanical aspects. The other phrases describe plausible job titles, but they do not reflect the standard licensure-based responsibility indicated by “of Record,” so they aren’t correct expansions of the acronym in this context.
